MACHINE FOR MAKlNG FRUIT BOXES.

SPECIFICATION forming part of Letters Patent No. 356,478, dated January25, 1887..

Application filed May 4, 1886.

To all whom it may concern.-

Be it known that I, BERNHART KEMPER, a citizen of the United States ofAmerica, residing at Muscatine, in the county of Muscatine and State ofIowa, have invented certain new and useful Improvements in Machines forMaking Fruit-Boxes, of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention relates to an improved machine for making fruit-boxes,which machine is constructed as hereinafter fully set forth and"claimed.

In the drawings, Figure 1' is a perspective View of my improved machine.Fig. 2 is a front elevation, in which a box partly formed is shown bythe full and broken lines, and a box completely formed, ready fornailing or riveting together, is shown by the full lines. Fig. 3 ispartly a vertical section and partly a front elevation. Fig. 4. is aplan view of a portion of the machine. Fig. 5 is a perspective view of abox formed as hereinafter ,set forth.

A A designate the standards of the machineframe, having their upperportions stayed by the side bars, a a, securely fastened to the edges ofthe standards the required distance below their upper ends. The lowerportions of the standards may be stayed in any wellknown manner. In thepresent case they are shown as stayed by a toolbox, B, securely fastenedto the inner sides of the standards. This frame of the machine may besupported in position by stays b,attached to one or both of thestandards.

O designates a rock-shaft having its bearings in the upper portions ofthe standards. This rock-shaft is made long enough for the front end toextend the required distance beyond the front standard, as shown.

D designates a square block plated with sheet-iron or other suitablemetallic substance, and is securely fastened centrally on or to theextended end of the rock-shaft. This block is made the size ofthe insideofthe boxes to be formed on the machine.

On the extended portion of the shaft, between the block and the frontstandard, is a pulley or wheel, I), loosely mounted on the shaft, toform the bearing of the strap 12*, the lower end of which is attached toa pedal, 0,

Serial No. 201,071. (MorleL) and the upper portion of the strap isextended over the pulley, and the upper end of the strap is attached tothe movable frame E, the rear end of which frame is pivoted or hinged tothe side bars, a a.

The rock-shaft is provided with a stop-pin, d, adapted to strike uponthe upper edges of the side bars, a a, of the machineframe, forming thusstops to the rocking movements of the shaft. pose of reversing theposition of the box to enable it to be nailed-on two opposite sides) bymeans of a strap, h, the pedal h, and the spiral spring if, placed uponthe shaft, and fastened at one endto the bar a and at the other end tothe shaft or the stop-pin. The lower end of the straph is attached tothe pedal h, and the upper portion is extended over and partly around,and has its end fastened to the shaft, so that downward pressure uponthe pedal will turn the shaft half-way around, being stopped by the pinstriking the top of the side bar, a; and the shaft is rotated in theopposite direction by the spiral spring till the pin strikes the topedge of the side bar, a.

The front portion of the movable frame is constructed to form a boxlarge enough to receive the block D and the box formed on it.

F designates thecentral portion of the boxformer, provided with thehinged flies c d, the same size as the central portion, which is thesize of one side of the boxes to be made on the machine. v

Two spiral springs, a are placed upon the bottom of the box of themovable frame, and

The shaft is rocked (for the purthe central portion, F, of the former isplaced on these springs, and is held in a horizontal position by themwhen no pressure is applied to the pedal 0, as shown in Figs. 1 and 2 ofthe drawings. The front end of the movable frame is provided with ashelf, .12 forming a convenient receptacle for tools and materials usedin making the boxes. The movable frame is provided with arms 0, havingpins 0 forming stops to the inner edges of the boards used for the sidesof the boxes.

The lower side of the block, near its inner face, is provided with lugsor pins d forming stops to the inner end of the board used for thebottoms of the boxes.

"When no pressure is applied to the pedals,

formed on the front standard.

the machine is in position shown in Fig. l of the drawings.- The board(1", cut the required size to form the side of a box, is placed on theformer, with the back edge against the stop-pins c, and the bottompiece, cl", cut the required size, is placed at right angles to and overthe side piece, immediately under the block, and with its inner endagainst the lugs d on the box, as seen in Fig. l of the drawings.Pressure being then applied to the pedal 0, the front end of the movableframe is thrown upward, causing the upper edges of the frame to impingeagainst and elevate the flies c d, bending upward the ends of the sidepiece, d, while the front strip, a", impinges against and bends upwardthe bottom piece, (1*. The ends of the side piece automatically inclineslightly outward, allowing space between them, as shown by dotted linesin Fig. 2 of the drawings, for the end of the bottom piece to be bentdown freely over the edge of the block. Then by hand the ends of thebottom and side pieces are bent down over the edges of the block in thefollowing order, viz: first, the end of the bottom piece, then the right-hand end, and, lastly, the left-hand end of the side piece, theleft-hand end lapping over the other end, as shown by full lines in Fig.2 of the drawings. Pressure being then removed from the pedal 0, and thefly 0 being held by hand in an upright position against the box, theweight of the frame causes the flange a to descend and bear upon theoverlapping end of the side piece, as shown in Fig. 2, holding in placethe folded ends while they are being nailed or riveted together. Whenthese ends have been thus fastened together, the flanged fly is releasedfrom the box, and the movable frame drops upon the rests f, Pressurethen being applied upon the pedal h, the shaft is rotated till the pin(1 strikes the top of the side bar, (4/, thus reversing the position ofthe block and box, so that the other end of the bottom may be securelynailed or riveted to the side piece. The box, being thus completed, isremoved from the block, and the machine is in position for theconstruction of another box in the same manner.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the frame of a machine for making fruit-boxes,of a rock-shaft, G, and a forming-block, D, fastened securely upon theextended end of the shaft and adapted to be reversed in position bymechanism, substantially as and for the purposes described.

2. The combination, with the frame of a machine for making fruit-boxes,of a reversible forming-block, D, a movable frame, E, having a box toreceive the block, and a box-former consisting of the central portion,F, and hinged flies c (1, adapted to bend the bottom and side pieces ofthe box around the block, substantially as and for the purposesdescribed.

3. The combination, with the frame of a fruitbox-making machi ne havingthe stay-bars a a placed below the upperends of the stand ards, of therock-shaft 0, provided with the stop'pin cl and the retracting spring h,the formingblock D, mounted centrally on the extended end of the shaft,the pedal h, and strap 71., attached to the pedal and shaft, substantially as and for the purposes described.

4. The combination, with the frame of a fruit-box-making machine, of arockshaft, (3, provided with a pulley, b, the reversible for1ning-blockD, mounted upon the extended end of the shaft, a movable frame, E,having a box to receive the block, a box-former consisting of thecentral portion, F, and hinged flies c d, Jlaced on yielding bearings inthe box ofthe movable frame, the pedal 0, and the strap 1), extendedover the pulley on the shaft and attached to the pedal and frame,substantially as and for the purposes described.

In testimony whereof I have atlixed my signature in presence of twowitnesses.

BERN HART KEMPER.
